辅助函数法在数学分析中的应用

The Application of Assistant Function in the Function Analysis

作辅助函数相当于作几何辅助线,它是解决问题的桥梁,这里给出了参数法、折线法、图形法等五种方法,它在数学分析的论证中有着很广泛的应用.

To create the assistant function is equal to create the assistant line it is the bridge of the solution to the problem. In this paper five methods are qiven such as parameter method broken-line method pdygonometry graph method etc. These methods are widely applyed in the proof of function analysis.
